I just purchased the aircraft and downloaded a United livery. When I ran the aircraft for the first time I ran the United one. The activation window that is described in the PMDG 777 Introduction PDF didn't come up. Is there any way I can get it to come up so I can fly the aircraft?

 

Thanks,

I believe there is an option under the FMC PMDG options menu that is labeled licensing or something similar.  I do not have the plane or manuals available to verify the correct menu.

 

If you cant find it or can not corrrect the issue I recommend requesting for support via the PMDG hompage.
